kind; for secrets are so seldom kept, that it may with some reason be doubted, whether the ancients were not mistaken in their first postulate, whether the quality of retention be so generally bestowed, and whether a secret has not some subtle volatility, by which it escapes imperceptibly at the smallest vent, or some power of fermentation, by which it expands itself so as to burst the heart that will not give it way.
Those that study either the body or the mind of man, very often find the most specious and pleasing theory falling under the weight of contrary experience; and instead of gratifying their vanity by inferring effects from causes, they are always reduced at last to conjecture causes from effects. That it is easy to be secret, the speculatist can demonstrate in his retreat, and therefore thinks himself justified in placing confidence; the man of the world knows, that, whether difficult or not, it is uncommon, and therefore finds himself rather inclined to search after the reason of this universal failure in one of the most important duties of society.
The vanity of being known to be trusted with a secret is generally one of the chief motives to disclose it; for however absurd it may be thought to boast an honour by an act which shews that it was conferred without merit, yet most men seem rather inclined to confess the want of virtue than of importance, and more willingly shew their influence, though at the expense of their probity, than glide through life with no other pleasure than the private consciousness of fidelity; which, while it is preserved, must be without praise, except from the single person who tries and knows it.
